WebBTB is a chemical indicator used to test for the presence of Carbon Dioxide. It is green because there is already some Carbon Dioxide in the solution. b. If snails use lungs to breathe, you can conclude that they release which gas into their environment as a result of respiration? Carbon dioxide Carbon dioxide gas is very correct. WebBromothymol blue (also known as bromothymol sulfone phthalein and BTB) is a pH indicator. It is mostly used in applications that require measuring substances that would have a relatively neutral pH (near 7). A common use is for measuring the presence of carbonic acid in a liquid. WebJul 13, 2012 · Abstract. The spontaneous reaction of diazonium salts on various substrates has been widely employed since it consists of a simple immersion of the substrate in the diazonium salt solution. As electrochemical processes involving the same diazonium salts, the spontaneous grafting is assumed to give covalently poly (phenylene)-like bonded films. discord restrict bot to one channel
